We set up tank and tankless water heaters.
A on-demand hot water system is better than a traditional water heater.
However, the first price of a instant hot water system is significantly higher than a standard 40 or fifty gallon tank.
One small cost with tankless heaters is the maintenance expense for flushing the system every 5 to six years.

Recommended Customer Reviews

My house was built in 1954 and I needed a shut off valve installed from the water line to the ice cube maker in the refrigerator. Marc came out and did a super job of installing this valve in the wall behind the refrigerator. He is very knowledgeable and very experienced and I highly recommend using Marc.

Marc was a lifesaver for my leaking grohe faucet. He was quick to reply to me upon my initial inquiry and has excellent communication and customer service! He let me know when he would be there, set a price before hand and was reliable through and through. So grateful to have found Marc for this event and all future plumbing needs! He truly is as good as all his 5 star reviews say he is.

Marc is a super hero!!! I had a Water Heater that blew out and Marc showed up same day. He is semi-retired meaning he can help anytime and he is a blessing. I am in Real Estate and have spent decades with Plumbers who don't show and take advantage of people. Marc is a god-send to homeowners in Lafayette and Orinda. He is a neighbor and now a friend. I have a 4 year old and 6 year old clogging toilets with TP and Marc recommended these newer toilets and it has been a game-changer. Rather than coming home to clogged toilets, I come home to a happy family. I cannot recommend him highly enough. 6 Stars!!! out of 5!!!

Marc Brenner went out of his way to help me fix my tankless water heater. Instead of setting an appointment . Then charging me for fixing my tankless water heater. He instead walked me thru some basic things that could possibly the problem.
Due to the fires the air induction filter are being clogged. Simple solution clean the mess filter and the system worked .
I want to thank Marc for being a honest and good guy .
Thanks Again Marc

Honesty is everything in the service industry when one is looking for a reliable technician. That, of course, includes getting the job done right. Marc Brenner is one of those guys. After interviewing four different plumbers, Brenner not only made the most sense in how he would approach my job but he offered the lowest price. And he did an excellent job, coming up with a creative solution to a tricky pipe leak. . And, it turns out he's my neighbor, which didn't hurt. Good guy. Highly recommended.

Marc came the same day I called and arrived on time. He replaced a bathroom faucet fixture that had been leaking. The job presented some challenges regarding access, but Marc persevered. He stuck with it and figured it out with great success. I am very grateful for his determination and a job well done. I will be calling on Marc in the future and highly recommend his expertise.

Marc talked me through lighting my pilot light on the phone for no charge. He facetimed with me and we got it lit. Such a great person! I really can't thank him enough!!

Once again, Marc saved my a$$. Old pipes = gas leak = PGE shut down gas = very angry wife. Couldn't get a hold of Marc, and time was of the essence, so called another plumbing company (big mistake) named after the guy on the $100 bill. First they quoted me $13,000 to repipe. Then, after bringing out ""the boss"" for a final look, told me it would really be $16,000 and they would get it done ASAP. I told them ""no"" as it seemed like they were taking advantage of the situation and the fact that I was desperate. When I got a hold of Marc and told him the story, he came out immediately to walk the site and figure out a solution. Less than a week later, I have a new gas pipe that PGE is happy with and most importantly, the wife is happy too. Total cost = $10,000. Thanks for saving me $6000 Marc!

I can't thank Marc enough for the help he gave me in resolving a burst water pipe at my
home. Unfortunately, Marc was booked and could not repipe my home; but he guided me through a difficult time with the course I should take in fixing my problem. Because Marc
couldn't do the work, I hired a plumber and had many questions along the way. I know if
Marc had been available I would have totally relaxed knowing that no short cuts would be taken and that the best job possible would be performed. Marc is a great person and a
forensic plumber!! He is the best!!!

Marc installed a new hot water heater and we plan to use him to install a new heater. Marc's a solo practitioner, clearly knows what he's doing, and is a pleasure to work with. He was also cheaper than some of the bigger companies out there. I'd use Marc again in a heartbeat. Strongly recommended.
